Abstract
The present invention provides a current sensor of smaller and simpler configuration, capable of measuring a current to be detected with high precision and stability. A current sensor has a V-shaped conductor line and a pair of magnetoresistive elements disposed along with the conductor line so that a resistance value of one of the magnetoresistive elements changes in a direction opposite to that of resistance-value-change of the other magnetoresistive element according to current magnetic fields produced by a current to be detected flowing through the conductor line.
